The Nikon® M-308 Rifle Scope is designed specifically for use with modern AR-platform rifles chambered in .308 Win. (7.62 NATO). The BDC 800 reticle model is meant to zero at 100 yards with holdover points out to 800 yards. The M-308 utilizes a side focus parallax adjustment knob for easily correcting parallax at varying ranges. Featuring 4-time zoom range, the M-308 gives users tremendous versatility for shooting where ranges are constantly changing. Nikon's Ultra ClearCoat™ Optical System produces sharp, high-contrast views of the target, and across the entire field of view at all magnification settings; the system enhances brightness for use in low-light conditions. The M-308 is constructed of an exceptionally rugged, single piece aircraft grade aluminum alloy tube. Windage and elevation adjustments hand-turn at 1/4-M.O.A., and have spring-loaded, zero-reset turrets. A quick-focus eyepiece and generous eye relief allow precise focus and protect the shooter's eyebrow from recoil. The Nikon M-308 Rifle Scope is nitrogen filled and O-ring sealed ensure waterproof and fogproof performance when shooting in adverse weather conditions.
